mysql-8.0.13安裝及部分操作

官網下載win64壓縮包；

我是解壓在c盤下新建的web文件中

然後打開C:\web\mysql-8.0.13-winx64，創建my.ini文件

文件內容

[client]
port = 3308
default-character-set = UTF8MB4
 
[mysqld]
port = 3308
character_set_server = UTF8MB4
 
basedir=C:\web\mysql-8.0.13-winx64
datadir=C:\web\mysql-8.0.13-winx64\data
 
group_concat_max_len=20000
 
 
[WinMySQLAdmin]
C:\web\mysql-8.0.13-winx64\bin\mysqld.exe

然後在管理員權限下的cmd中選擇進入其中的bin目錄

cd C:\web\mysql-8.0.13-winx64\bin

接着輸入

mysqld --initialize --console

出現密碼+V0x;iq!7n=F，並報了一個錯誤，不過我在之前的代碼中已經改了過來。

C:\web\mysql-8.0.13-winx64\bin>mysqld --initialize --console
2018-11-30T03:44:42.553357Z 0 [System] [MY-013169] [Server] C:\web\mysql-8.0.13-winx64\bin\mysqld.exe (mysqld 8.0.13) initializing of server in progress as process 60624

2018-11-30T03:44:46.075302Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: +V0x;iq!7n=F

然後是創建服務器和創建用戶

C:\web\mysql-8.0.13-winx64\bin>mysqld --install MySQL8.0 #安裝服務
Service successfully installed.

C:\web\mysql-8.0.13-winx64\bin>net start MySQL8.0 #開始服務，服務器名MySQL8.0

C:\web\mysql-8.0.13-winx64\bin>mysql -u root -p #登錄
